Since I'm using MinGW binaries in 32 bit and 64 bit mode (as plugins for flight simulator applications which exist in 32 and 64 bit), I would be very happy to have both as official MinGW installers. Especially since the MinGW debug binaries are huge compared to the MSVC ones. So I tend to use 64 bit ones (up to now self compiled from source) whenever possible.
Would it be an option to add the MinGW 64 bit installer and keep the 32 bit one?
